Randall Grahm from Bonny Doon Vineyards is hosting a Live Chat in the forums on http://www.wildoats.com. Accoring to the website, he'll be in the forum to answer questions on Wednesday, June 14 from 4-6 PST but you can post questions now and come back for the answer at another time.

From what I understand Mr. Grahm is quite the genius and I'm sure he'll have lots of interesting (if not entertaining) things to share.
